integral of xsin(x)y

\int x sin (x) y d y

\frac{x}{2} y^{2} sin (x) + C

Solution steps

\int x sin (x) y d y

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= sin (x) x \cdot \int y d y

Apply the Power Rule

= sin (x) x \frac{y ^{2}}{2}

Simplify

sin (x) x \frac{y ^{2}}{2} : \frac{x}{2} y^{2} sin (x)

= \frac{x}{2} y^{2} sin (x)

Add a constant to the solution

= \frac{x}{2} y^{2} sin (x) + C
